Steel Forged Sleeves
- Material Versatility: Stainless steel, alloy steel, carbon steel, and custom grades upon request.
- Dimensional Precision: Machining accuracy controlled within ±0.02 for critical tolerances.
- Wide Size Range: Produced fully according to customer drawings and special sleeve geometries.
- High Mechanical Strength: Forged sleeves reach tensile strength levels of 550–950 MPa depending on steel grade.
- Large Production Capacity: 500–1000 tons/month with CNC loading up to 32 tons (machining) and 70 tons (heavy-duty).
